IMPROVEMENT IN SEWING-MACHINES.

fltlge gtlgvhule march in in time ilrttn s time at making part at its smut.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, DAVID FORREST, of Eastport, in the county of Washington, and State of Maine, have invented a new and useful Improvement in Hand-Lever Sewingl\lachine for Patching Boots, &c.; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being bad to the accompanying drawing, forming part of this specification, in which the drawing represents a side elevation of my improved hand-lever patching-machine.

The nature of this invention consists in a device for sewing patches on boots and shoes, and other similar articles, by means of a hand-lever to work the needle, the construct-ion of which is hereinafter explained.

Upon the side of a bench or table, A, a long and stout metal-frame base, B, is fastened at the end. The base, 13, may be cylindrical or square, and supports an overhung frame, G, the front end of which serves as the arm, C, for the socket b of the needle a. At the outer end of the base, B, is a cap-shaped bed-plate, a, through which the point of the needle works to sew the material, under which bed-plate is the chain-stitch loop-hook d, the toe of which is set in a recess at the end of a sliilebar, 2, running along the base A to the back end, where it is pin-jointed to the end of a lever, 9', having its fulcrum centrally at h, and connected 'by pin-joint at the Opposite end to a slide-bar, k, on the end of which is a head, m, provided withia perpendicular slot, in which plays a projecting hook, u, made fastto a bent hand-lever, D, pivoted at s, on the extremity of the outer arm of which bent lever is the needle-stock p. The spool of thread sets on the spindle g.

It will be seen that by working the hand-lever, the needle will operate on the material placed on the bedplate 0, and a boot or shoe or other similar article can he slipped over the base, A, for the purpose of sewing on patches.

Having described my invention, I claim as new; and desire to secure by Letters Patent- The beat hand-lever D, in combination with the slide-rodeo 7c, mounted on the base, 13, and connected with the needle a and the looper d, as set forth, the whole constructed and operating asherein described.

DAVID FORREST.
